Dear Users: Thank you for purchasing multifunction series digital readouts. Digital readouts are used in a wide variety of application. These include machine tools, infeed axes, measuring and inspection equipment, EDM, dividing apparatuses, setting tools, and measuring stations for production control. In order to meet the requirements of these applications, many encoders can be connected to the digital readouts. Read all the instructions in the manual carefully before used and strictly follow them. Keep the manual for future references. Safety attention: z To prevent electric shock or fire, moisture or directly sprayed

cooling liquid must be avoid. In case of any smoke or peculiar smell from the digital readout, please unplug the power plug immediately, otherwise, fire or electric shock may be caused. In such a case, do not try to repair it, please contact the Company or distributors.

z Digital readout is a precise measuring device used with an optical Linear Scale. When it is in use, if the connection between the Linear Scale and the digital readout is broken or damaged externally, incorrect measuring values may be resulted. Therefore, the user should be careful.

z Do not try to repair or modify the digital readout, otherwise, failure, fault or injury may occur. In case of any abnormal condition, please contact the Company or distributor.

z If the optical Linear Scale used with the digital readout is damaged, do not use a Linear Scale of other brand. Because the performan ce, specification and connection of the products of different and can not be connected without the instruction of specialized technical personnel, otherwise, trouble will be caused to the digital readout.

The memory is used to store the settings of the DRO and machine reference values when power is turn off.

17

General Operations

4.9 Search the Absolute Reference Point of Scale During the daily machining process, it is very common that the

machining cannot be completed within one work shift, and hence the DRO have to be switched off after work, or power failure happen during the machining process which is leading to lost of the workpiece datum (workpiece zero position), the re-establishment of workpiece datum using edge finder or other method is inevitably induce higher machining in accuracy because it is not possible to re-establish the workpiece datum exactly at the previous position. To allow the recovery of workpiece datum very accurately and no need to re-establish the workpiece datum using edge finder or other methods, every Linear scale have a ref point location which is equipped with ref position to provide datum point memory function.

The working principal of the ref datum memory function are as follows.

Since the ref point of Linear scale is permanent and fixed, it will never change or disappear when the DRO system is switched off. Therefore, we simply need to store the distance between the ref point and the workpiece datum (zero position) in NON-Volatile memory. Then in case of the power failure or DRO being switched off, we can recover the workpiece datum (zero position) by presetting the display zero position as the stored distance from the ref point.

An absolute datum should be set when a work-piece is machined. There are three mode operation (REF、AB、LEF_AB):

Example: to store the X axis work datum.

X axis ref mark position(permanent and fixed)

200 Groups SDM coordinate 5、200 Groups SDM coordinate The DRO has three display modes: the absolute mode (ABS),the incremental mode (INC) and the 200 groups second data memory (SDM 1 – SDM200). ABS datum of the work-piece is set at the beginning and the 200 groups SDM is set relative to ABS coordinate. ABS Mode, INC Mode and SdM Mode are specially designed to provide much more convenience features to the operator to cope with the batch machining of relative works and the machining of the workpiece machining dimensions from more than one datum. Example: The ABS datum is the center point O, the point sdm1, sdm2, sdm3, sdm4 needed processing are set as datum of SDM 1 –SDM 4.

Two ways to set SDM coordinate:

1、 Zeroing at the Current Point. 2、 Preset datum of SDM coordinate.

5.1 Zeroing at the Current Point At first set the center point of the work-piece as the origin of the ABS, then align the TOOL with point sdm1,sdm2,sdm3,sdm4 by moving the machine table and zero them. It is the position to process where the “0.000” appears in X window, Y window by moving the machine table whether in ABS or in SDM coordinate. Steps:

1、 Move worktable to place the TOOL at the center of the workpiece point O as the datum of ABS. Then zero X axis and Y axis in SDM 1 ; Zero X axis and Y axis in SDM 2 ; Zero X axis and Y axis in SDM 3 ; Zero X axis and Y axis in SDM 4.

EDM 6.10 EDM 1、 Description: This function is used for the special machining of Electro Discharge Machining (EDM). When the set target value of EDM Z- axis is equal to the present value, the digital readout will output the switch signal to control EDM to stop the depth machining. The setting of Z-axis direction the Digital Readout is shown as Fig 1, i.e. The deeper the depth is, the large the coordinate value of Z-axis displays. Since starting machining, the depth will gradually deepen and Z-axis. According to the set Z-axis direction, the machining direction is divided into positive and negative machining. When the electrode descends and the machining is carried out from up to down, the digital readout value will increase, which is called positive machining (Positive). The setting of this direction is the normal setting. When the electrode ascends and the machining is carried out from down to up, the digital readout value will decrease. The machining direction is negative direction (negative), which is also called negative machining (shown as Fig.1)

The Digital Readout also features other functions, such as negative fire proof-height. Negative fireproof height function is a kind of intelligent position follow check safety protective device. In the process of machining, the electrode surface will generate the carbon accumulation phenomenon. Due to the long-time or diurnal machining without tending , when generating the carbon accumulation and nobody makes the cleaning, the electrode will slowly increase along the negative direction. Once the electrode exceeds the liquid level, it will frequently catch fire and cause losses. This function is just set to aim at this problem. When setting negative fireproof height, and the increased height of electrode exceeds the height between it and the depth of machined surface (i.e. Negative fireproof height), the digital readout display will blink for waring; at the same time, the output signal will automatically turn off EDM to eliminate the fire chance.
